TURBINE WATER-WHEEL.

SPECIFICATION forming part of Letters Patent No. 569,613, dated October 20, 1896. Application filed May 20, 1896. Serial No. 592,362. (No model.)

To all whom it may concern.-

Be it kn own that we, JAMES CALDWELL and EMERY GALDWELL, of Auburn, in the county of Cayuga, in the State of New York, have invented new and useful Improvements in Turbine ater-lvheels, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to improvements in turbine water-wheels, and more particularly to the construction of the chamber which admits the water to the wheel.

Our object is to improve the construction and operation and general utility of turbine water-wheels, so as to be able to utilize a minimum amount of water for the purpose of increasing or decreasing the power, and the further object of avoiding the carrying of dead-water; and to that end our invention consists in the several new and novel features of construction and operation hereinafter described, and which are specifically set forth in the claims hereunto annexed. It is constructed as follows, reference being bad to the accompanying drawings, in which Figure 1 shows a top plan viewof the chamber containing the wheel, one of the quartergates being raised. Fig. 2 is a side view thereof, one portion of the chamber being broken away to show the wheel.

Similar letters of reference indicate corresponding parts.

A is the case, preferably cylindricalin form and provided with a cover to, having openings 1) near its outer edge directly over vanes or spiral buckets 0 upon the drum B, which together form the wheel. To the drum B is I a vertical shaft 0, which transmits the power in the ordinary way.

d cl are quarter-gates,and e one-sigh th gates, or they may be divided up into any other size or sizes which may be desired, and are suitably hinged to the top a and provided with means, such as the chains f, passing over the fixed pulleys g, for operating them.

It will be observed that when we desire but a small amount of power a large or a small gate maybe raised to suit the convenience of the amount of power required. It will also be observed that by admitting the water from the top to the buckets and allowing it to pass out at the bottom as soon as the forceis spent we are able to obviate the carrying of deadwater a certain distance, as is the case with all other turbine wheels which admit the water from the side.

What we claim as our invention, and desire to secure by Letters Patent, is-- A vertical wheel, and a vertical inclosing case that is open at its bottom, and provided at its top with a series of openings of different sizes, combined with a series of verticallynioving gates which correspond in size to the openings in the top of the case; the posts rising from the top of the case, the guidingpulleys on the posts, and a separate chain for each gate, substantially as shown.

In witness whereof we have hereunto set our hands this 8th day of May, 1896.
